MILK sTERlLlzER on PAsTEuRlzEn.

Patented Dec. 5., 1905.

To aJ/Z whom it may concer-721.

Be it known that I, FRANK H.- MORSE, a citizen of the United States, residing at Savannah, in the county of Chatham and State of Georgia, have -invented certain new and useful Improvements ineMilk Sterilizers or Pasteurizers; and I do hereby declare the followingto be a full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the art to which it appertains toV make and use the same, reference being had to the accompanying drawings, and to the which form a part of this specification.

This invention relates lto new and useful improvements in an apparatus for sterilizing or pasteurizing milk and other liquids; and the object of the invention is to produce a simple and efficient apparatus whereby milk may be quickly and -t oroughly treated by first passing the same through sand upon 'a wire-gauze and afterward heating the same by means of a heating agent assing through coils and afterward cooling t e milk.

The invention consists in various details of construction and in combinations andA arrangements of parts, which will be hereinafter -fully described and then specifically deined in the appended claim.

My invention is illustrated in the accomp anying drawings,

application, and in which drawings- Figure 1 is a vertical sectional view through paratus, and Fig. 2 is an enlarged sectiona view through the tank containing the sand and wire-gauze.

Reference now being had to the details of the drawings by letter, A designates a receptacle having a series-of transverse gauze partitions B, upkon which sand E is adapted to be placed, t e mesh of the 'gauze being such as to Eievent the particles of sand from passingV t ough the gauze, and

steam is adapted to be passed, and F desig-l .per G, formed which, with the letters of` reference marked thereon, form a part of thisV C designates a discharge-pipe leading from the rece tacle'B n D is ay nates a discharge-pipe leading from'the bottom of the tank D and emptying into a hopat the upper end of a tank H. I-he tank H is surrounded with a coil of pipe K, through which a cooling liquid is adapted be passed for the purpose of reducing the ,temperature of the milk after coming from ,the tank D, and a discharge-pipe I leads .from the tank I-I and communicates with a tank N, which has a coil of pipe O passing l'about the same, through which a refrigerating agent is adapted to be passed for the purpose of still further reducing the temperature of the milk before it`makes exit through a discharge-pipe J into any suitable receptacle for storage.

. From the foregoing it will be vobserved that by the provision ofthe apparatus shown and described a sim le and efficient means is provided for quic y treating milk by first causing the same topass through sand and gauze partitions su porting the same and afterward to be heate and cooled in the .manner described, thus thoroughly eliminating all forms of bacteria 'or foreign matter from the milk.

Having thus fully'described myinvention, what I claim as new, and desire to secure by Letters Patent, isf A'pasteurizing apparatiiscomprising a receptacle, gauze partitions within the same and a filtering medium of sand supported by said partitions, a tank communicating wit said receptacle, a cQil about the circumference of said tank through which hot water or steam is adapted to pass, acoolingtank communicating with the tank about which hot Water or steam circulates, a third tank adapted to receive the milk from the tank about which theA cooling agent circulates, and refrigerating-coils about said third tank, as shown and described.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

FRANK H. MORSE. Witnesses:

W. R. HEWLETT, K. G. LAFFITTE.
